Remote sensing imagery has been widely used in urban growth and environment analysis with many effective and advanced strategies being developed. However, most of these approaches are separated from each other. There is an urgent need to combine different modules into some practical processing chains. Firstly, we present a comprehensive analysis of key processing chains in applying remote sensi...

The decision to upgrade Enterprise Systems (ES) is influenced by various factors, which are either internal or external to the organisation. Although previous studies have explored these factors, the majority of these studies have focused on Enterprise Resources Planning (ERP) systems only. Thus, this study through a qualitative survey design draws from the expertise of 41 respondents represent...

Holland’s Schema Theorem is widely taken to be the foundation for explanations of the power of genetic algorithms (GAs). Yet some dissent has been expressed as to its implications. Here, dissenting arguments are reviewed and elaborated upon, explaining why the Schema Theorem has no implications for how well a GA is performing. Interpretations of the Schema Theorem have implicitly assumed that a...

In this paper we address two issues in modeling natural terrain using fractal geometry: estimation of fractal dimension, and fractal surface reconstruction. For estimation of fractal dimension, we extend the fractal Brownian function approach to accommodate irregularly sampled data, and we develop methods for segmenting sets of points exhibiting self-similarity over only certain scales. For fra...

2/ Professor of Landscape Architecture, University of California, Berkeley. Landscape Architect, Pacific Southwest Forest and Range Experiment Station, Berkeley, Calif. Abstract: Descriptive landscape analyses include various procedures used to document visual/scenic resources. Historic and regional examples of landscape description represent desirable insight for contemporary professional inve...

Just 50 years ago, large herbivores like Banteng, Asian Elephant, and Eld’s Deer as well as predators like Indochinese tiger and leopard were so abundant in the Dry Forests of North and Northeast Cambodia that scientists compared this ecoregion to the savannas of East Africa. In the troubled decades that followed, however, habitat destruction and hunting greatly reduced animal numbers and diver...

Projects are the executors of organizational change and hence in charge of the managed evolution of the application landscape in the context of enterprise architecture (EA) management. Although the aforementioned fact is widely agreed upon, no generally accepted information model addressing the challenges arising in the context of future planning and historization of management decisions concer...

a r t i c l e i n f o We outline several diversity factors that modellers and models can include directly or indirectly in order to improve the accuracy and usefulness of the model. Without considering these factors, different types of diversity deficit can arise. These deficits can be considered in three domains: 1) in the real world where actual diversity is less than a potential state that i...

To the uninitiated, and even the old hand, the computer industry is an intimidating agglomeration of firms, markets, and buyers, all changing quickly in response to the latest innovation or recently invented applications. Technological opportunities arise rapidly, altering the technical landscape more quickly than in any other industry. Established firms feel perpetually under siege, particular...

Expert knowledge plays an integral role in applied ecology and conservation (Burgman 2005 ) . Environmental systems are characterized by complex dynamics, multiple drivers, and a paucity of data (Carpenter 2002 ) . Action is often required before uncertainties can be resolved. Where empirical data are scarce or unavailable, expert knowledge is often regarded as the best or only source of inform...
